Runtime Object Identification issue

In a flex application, there are three Edit box and they are identified by TestComplete as:

obj1 = obj.TextArea("mainEditor")  ---- this is working fine

obj2 = obj.TextArea("mainEditor",1)  --- during runtine this is not identified, instead of clicking on this object the click is performed on obj3

obj3 = obj.TextArea("mainEditor",2) ---- this is working fine



Any suggestions??



Thanks In advance
